Values are means ± SD, n = 30, for circulating concentrations of lactate (Energy Balance (BAL): A, Energy Deficit (DEF): B). Time points not sharing letter (a, b) are different from one another, P < 0.05. Data analyzed using mixed Model ANOVA with Bonferroni correction to determine the main effect of energy (BAL vs DEF), treatment (20% vs 40% vs 60%), time, and their interactions
